To all 'whom t-umy concern:

tion and operation of the saine, reference being had to the annexed drawings, inaltingpart ot this speeiticatioii, in which- Figure] is a longitudinal elevation. Fili-.'-

view ofthe ceiling-cylinder, enlarged to -show more plainly its construction. Fig.` 4 is a view ot' one ot' the guide-wheels and partol' the coiling-eylinder, also enlarged so as to iiiore l'ully 'show it` construction.l the letters ol" referv ence on all the ditl'ereiit tigures corresponding.

The natiii'eot' niyiiivention consists in a cuit-- ahlc spiral-grooved cylinder and two giiidewheels. so arranged that a piece of metal pipe can he coiled on the groove-d cylinder without much altering its cro` section hy bending;

also, iii tliepecnlar arrangement ol' the coiling cylinder, wherehy the cylinder and tinishcd eoil may be removed from the shaft ol'the machine andthe cylinder he removed t'roni theeoilwithont. injury to the coil or cylinder.

The construction and operation of iny nia` -chnie are as follows On a suitable hed,A, are placed two stands, i y

l' groove inthe cylinder, in connection with thc B, in which revolves the shaft C hy means o the hand-lcvers l) or suitable gearing. One end ofthe shaft C projects heyoiid the hearing-stand B, and carries the grooved eoilingcylinder 1" is a iiiovalile plate under the coilingcylindcr E. One end ol' this plate is supported on a screw-jack, G ;thc' otherlend is hinged into a,

frame, ll, which t'i'aii'ie slides vertically in the i stand B, and is raised and lowered hy means of anotherjack-screw; G. b'car each end ot -the plate F is fastened the ninall istandsl l.

Through the eye ot' thesefstands passes the shaft J J. On-.thia-nhz'iit, near eachend and inside of I I, are, placed thc triangular pieces K K, which pieces are free tovihratc ou the shaft .l .l through thc.two upper liolesof l( K, and,- connect in g-t'heni, pass tho gindewhcel shafts L L. 0n these shafts are placed the guide-wheels )l M These wheels have turned hito their foce a, seniitzircuhirgrocve, which caws fs'v 'lated August. 30 1659 groove, iii coiinectio groove in the liottoniot' thesqnare groove ons' the ceilingcylhitler,-tornislaftrue circle-ofthe 1 diameter-ofthepipe-t0 hecoilcd.:

'The coding-cylinder E isiconipenedof a ntiinherot' stares, with thcfj'oiiitisradiatingl .f from the center, except thejoints ofthe-stave N, which radiate' in an oppositedirection; thus forming :i hey-stave, the largest part of which is toward the centerof tlie.cylinder. This ltey-stave u keeps and `tightens thefotherf lstaves in their position -in the hoops=f0 0.

The cylinder hasy now the appearance ofa -coininon straighbsided harrel,with'close-lit l tngjoints of the stares.' 0n the circumfer enccot' the cylinder worked; spirally av4 square groove (sa y, for a cylinder to .bend twoilich-diaincter pipe) -oiicfhall' iiiclrdcep and -two and onehalf inches wide. Injthe bottom ot' this' square groove is now worked theseniicircular groove two inches diameter; .This leave@` a'iixotl'sctv inthc-square 'groove .of onct'onrth inch on` each sideof the iseinieirclcV groove. The guide-wheels M M (for same size-d groove) nieastiijet wo and one-liail'inclies on the t'ace and have the seinicrcular groove of two inches diameter turned onto theirtace. These wheels, itV will he observed, rnn in tlicsqnare groove ol' Athe cylii'idcr which groove causestlie guide-wheels to follow the groove in cylinder l, and at all places and 'positions the groove in the guide-wheel, forms a perfect circle of the. diaineterotthe'pipc to he coiled.

that one ot tlie,guid'e-wheels is placed immo datcly under the center o f the cylinder E aud in contact with it. The second guide-.wheel ll placed beyond the that, also in contact with `n 1 with thc se-iiucircularv The ohjectia radiating the. jointtiof the stavcN of the cylinder and prevents it making short kinks,while the second-wheel rounds up the pipe and causes it topreserve its` cross-section.

The c ve or .holes of the guide-wheels are made bell mouthed, as shown at Iig.' 4. -This allows them (the wheels) to follow the groove o'n the j perfect coil mustbe rounded up after leav ing this pointe,

The manner ot'operating iny niachine-is'as vfollows: Ihe pipe being heated in asuitable `furnace, such as is used b v pipe-Welders, isj- United States,'is-

brought tothen'iachinc.' 'The screw-'jack G,

carrying the hinged end oftheplate I", issuflcientl) lowered to allow the pipe to pass between the guide-'wheelsland c vllinder. ,.gQlhe I pipe being inserted, the screw'jackis raised until the guide-wheels. come in contact with the oii'set in the groove onthe cylinder, when 2.

the pipe is fastened by a key to the lug S, east ou the cylinder. The cylinder, beingnow-put-v in motion, coils the pipe in the groove, the

guide.\\'lieels operating a's herein described. When the -coil is completed, the jackscrews .are lowered so as to clear the pipe,'the 'set-l screws I are loosened, and the coil and cyln- E der removed. from the shaft. The screwsf holding the keystave N are removed, and the 1 E,t hcse guide-wheels running, as above stated,-' inthe square part of the groove on' E.' v,The

For this reason' I-introdnce the; second wheel' to counteract this flattening and preserve the vcr0ss-sectionof the pipe.
